Weslaco Independent School District formed in 1921, when residents petitioned the Texas Legislature to separate from Donna ISD. Upon the district's creation, board members planned for the first school building, designed by San Antonio architect Harvey P. Smith and completed by Brownsville's H.L. Fitch and Co. by Feb. 1923. The one-story school building with raised basement is built of reinforced concrete and hollow tile, faced with dark Butler brick and lighter bands near the floorline. The recessed central entry has a prominent door surround and pediment. The structure and adjacent Weslaco Junior High were threatened with demolition before being rehabilitated for the 2006-07 school year.Recorded Texas Historic Landmark-2009
